When 16-year-old Joseph Kinville III is brutally stabbed to death in a field in his neighborhood in Arcadia, Florida, law enforcement is stumped from the start and his mother is devastated. The mystery only deepens when the teen's estranged father is murdered a few weeks later, hundreds of miles away in Michigan. The identity of Joseph's murderer has remained unknown since his murder in 1999, but evidence from his crime scene may still hold the answers law enforcement needs.
